Definitions
- the invention relates to optical elements made of optically isotropic plastic and in particular those made of a fully aromatic polyester with a glass transition temperature T g > 180 ° C.
- Organic polymers are increasingly interesting materials for applications in optics, micro-optics, integrated optics, optical communication technology and microsystem technology. They are used in a variety of ways in optical device parts and in special optics as lenses, lens arrays, prisms, mirrors and as a transparent coating material for optical components. There is a great need for optical components, above all in optical communications technology, optical connection technology and optical sensor technology. Required components are e.g. B. splitters, couplers, beam deflection units, optical switches and attenuators. In addition to typical semiconductor materials, organic polymers are particularly suitable for the production of these optical elements.
- Polymers can generally be processed in a technologically advantageous manner, for example by injection molding, stamping technology or else from solution.
- the desired characteristics of such polymers for optical applications are the lowest possible optical attenuation at the relevant wavelengths (preferably 1.3 or 1.5 ⁇ m in optical imaging technology), high moisture resistance, the highest possible temperature stability, in particular of the optical properties, and a refractive index variability to adapt to certain requirements of the component and a favorable processability.
- the use as a waveguide places manifold demands on the polymer.
- the refractive index of the material should be as variable as possible and adaptable to certain substrates.
- low material absorptions at 1.3 and 1.5 ⁇ m are required, ie optical losses of less than 1.0 dB / cm.
- the loss due to volume defects (inhomogeneities, microbubbles) must be minimized.
- adapted expansion coefficients and low shrinkage are prerequisites for the use of polymers for waveguide structures in integrated optics.
- thermal long-term stability of the mechanical and optical properties in the temperature range of> 80 ° C. is particularly desirable.
- the known simple thermoplastic polymers with good optical properties such as polymethyl methacrylate or polycarbonate are unsuitable for such long-term use temperatures.
- the glass transition temperatures of these polymers are only around 105 or 130 ° C., so that there is no longer any permanent stability.
- polymers with glass transition temperatures of> 180 ° C are preferred.
- high-performance plastics are polyimides, polyetherimides, polyaryl sulfones, polyaryl ether ketones or polyaryl ether sulfones.
- these are mostly difficult or difficult to process due to their relatively limited solubility or a complicated tempering regime.
- Polyesters are also known to have good optical properties, see EP-A-0 242 959, EP-A-0 184 716, EP-A-0 076 133.
- glass transition temperatures of> 180 ° C are only acceptable to obtain fully aromatic polyesters or polyarylates.
- polyarylates tend to form partially crystalline, liquid-crystalline or crystalline phases, which would significantly restrict their use as optical materials due to the high scattering losses which then occur.
- the above-mentioned documents also only describe optically anisotropic polyesters.
- isotropic, amorphous polyesters are required.
- Isotropic polyesters which contain 9,9-bis [4- (2-hydroxyethoxy) phenyl] fluorene as the diol component, see EP-A-0 653 451, EP-A-0 396 418, EP-A-0 380 027.
- EP-A-0 653 451, EP-A-0 396 418, EP-A-0 380 027 have relatively high optical losses at the wavelengths relevant to communications technology and z. T. clearly too low glass transition temperatures.
- the invention was therefore based on the object of selecting those polyesters which are composed of the simplest possible monomer units which, on the one hand, have sufficient glass transition temperatures> 180 ° C. and a low optical one Attenuation at 1.3 or 1.5 microns and have good processability, but on the other hand show no crystalline, partially or liquid crystalline phases, and can be processed into optical elements.
- the fully aromatic polyesters used according to the invention which have a glass transition temperature of T g > 180 ° C., are preferably fully aromatic copolyarylates. Of course, homopolyarylates can also be used.
- the building blocks for the fully aromatic polyesters are in particular the aromatic dicarboxylic acids and aromatic dihydroxy compounds mentioned below.
- copolyarylates found are preferably obtained from mixtures of aromatic dicarboxylic acids and aromatic dihydroxy compounds. These polyarylates are characterized by optically almost amorphous properties, by good solubility in paint solvents, by the low optical attenuation at 1.3 or 1.5 ⁇ m and by good film formation. The glass transition temperatures of these copolyarylates are above 180 ° C.
- Dicarboxylic acids based on the following structures are particularly suitable for the optical elements according to the invention
- R stands for hydrogen or fluorine
- R can independently stand for H or F.
- suitable for the production of the polyesters used according to the invention are derivatives of benzene, naphthalene, biphenyl, diphenyl ether, diphenyl sulfone and diphenylmethane, in each case with 2 hydroxyl or carboxy functions, which have one or more hydrogen atoms and / or fluorine atoms and / or methyl groups and / or may have trifluorenethyl groups as substituents.
- polyesters used according to the invention advantageously have a molecular weight in the range from 8,000 to 250,000, preferably from 12,000 to 120,000.
- the copolyesters produced by a polycondensation reaction have glass transition temperatures of T g > 180 ° C. They are readily soluble in customary paint solvents, such as cyclohexanone, ethoxyethyl acetate and methoxypropylacetate, and can be processed into transparent films or layers by spin coating or dip coating. Their refractive index at 633 nm is 1.4 to 1.6, preferably in the range from 1.45 to 1.57. According to the invention, under certain copolyester compositions, amorphous, non-crystalline polymers can be obtained which show little scatter at 1.3 or 1.5 ⁇ m. The optical losses at these wavelengths were determined to be 0.1 to 0.5 dB / cm.
- polyesters are known in the art, but non-crystalline, amorphous, non-scattering optical materials can be produced in particular with the copolyester compositions mentioned.
- copolyesters are for the production of waveguide structures, lenses, prisms, corrected "lens systems, optical fibers and carriers for optical layers as well as for many other needs.
- the amorphous copolyesters found can be obtained by copolycondensing mixtures of aromatic dicarboxylic acids with mixtures of aromatic dihydroxy compounds.
- the above-mentioned monomer units result in non-crystalline, amorphous polymers.
- the refractive index of the copolyesters described can be adjusted by varying the copolymer composition, so that the refractive index meets certain requirements, e.g. B. substrate, waveguide configuration, tuning core and cladding material can be specifically adjusted.
- the glass transition temperatures of the copolyesters according to the invention are in particular in the range from 180 to 270 ° C., but particularly preferably between 180 and 220 ° C.
- the polyester materials described are characterized by very low losses at 1.3 or 1.5 ⁇ m in the range from 0.1 to 0.5 dB / cm.
- the easy processability of the materials according to the invention is given by the fact that they are highly soluble in typical paint solvents, such as. B. cyclohexanone, ethoxyethyl acetate and methoxypropylacetate, and can thus be processed by spin coating or dip coating to form optical layers or films.
- typical paint solvents such as. B. cyclohexanone, ethoxyethyl acetate and methoxypropylacetate
- High-solid coatings with thixotropic adjustment can be produced from the copolyesters described, which allow processing by screen printing. On this basis, optical chips with the following shaping writing can be produced cost-effectively.
- the copolyesters according to the invention can also be processed by molding and embossing technology and by injection molding.
- the polyester obtained has a molecular weight of 48,000 g / mol and a glass transition temperature of 209 ° C.
- Amorphous, optically isotropic films in the ⁇ m range are obtained from methoxypropyl acetate by spin coating.
- An optical attenuation of 0.44 dB / cm and a refractive index at 633 nm of 1.540 are measured on planar waveguides at 1.55 ⁇ m.
- Benzyltriethylammonium chloride are dissolved at 5 ° C in 21.2 ml of 1 molar sodium hydroxide solution. 5 mmol of terephthalic acid dichloride and 5 mmol of isophthalic acid dichloride, dissolved in 23 ml of dichloromethane, are added with vigorous stirring. After 40 minutes, the polyester obtained is precipitated in weakly hydrochloric acid hot water. The precipitated product is washed with hot water and dried. The polyester obtained is purified by dissolving in THF and precipitating in methanol. 3.88 g of polyester are isolated (83.2% of theory).
